GENERAL DESCRIPTION
The ADA4004-1 and ADA4004-2 are single and dual precision bipolar op amps that featuring a 1.8 nV/√Hz precision, 40 μV offset, 0.7 μV/ºC drift, 12 MHz bandwidth, and low 1.7 mA/amplifier supply current. The ADA4004 is designed on the high performance iPolar™ process, enabling improvements such as reduced noise and power consumption, increased speed and stability, and a smaller footprint size. Novel design techniques enable the ADA4004 to achieve 1.8 nV/√Hz voltage noise density and a low 6 Hz 1/f noise corner frequency while consuming just 1.7 mA/amplifier. The small package saves board space, reduces cost, and improves layout flexibility. Applications for these amplifiers include high precision controls...
